Accuracy capabilities

Equipped with a dosing pump that offers an unmatched 40,000 step accuracy
Save and store up to 100 titration methods (either user-defined or standard). Customize methods to fit specific application needs or testing requirements. Easily program this titrator with standard methods that are in accordance with affiliations like ISO, ASTM, AOAC, AOCS, EPA and more
Operators can program this titrator unit with notification reminders for when to standardize the titrant
This titrator automatically calculates the average titer value and users can update the nominal concentration in the sample methods with the press of a button
Track progress in real-time. All important information is shown on the titrator’s large LCD screen. Use the live titration curve during analysis to quickly recognize patterns and spot potential problems
Achieve high speed analysis without sacrificing accuracy with dynamic titrant dosing. This occurs by adjusting the volume of titrant dosed according to the mV response from the titrator reaction
Get more accurate measurements with automatic drift rate compensation. This corrects the titration calculation to account for the effects of any moisture that may enter the cell
Choose the endpoint termination criteria based on mV stability times or drift rates with the dual platinum pin electrode
Maintain data quality with the titration results averaging feature. Ideal for those operators who consistently run replicates of samples. The successive results from a titration method are averaged along with the standard deviation
Attain a reliable starting baseline with the multistage analysis. This works well for users that test multiple sample types with different methods for each

Durability and design details

Manufactured to stand up to the harsh solvents and reagents used during titrations
Made with tough, chemically resistant materials including a strong casing as well as PFTE tubing with glass and stainless-steel components
Convenient-size, fits perfectly into any lab space
Simple to set up and user-friendly. Perfect for labs and businesses that have multiple personnel shift changes throughout the day
Intuitive screens and menus help operators navigate this titrator unit easily without getting lost in a nest of information

Safe and important operation features

Introducing a solid or liquid sample to the titration vessel is simple and straightforward. Includes a quick-remove sample port with a replaceable rubber septum
Equipped with a sealed solvent management system and built-in air pumps. Users can move the reagent into waste and refill without physically touching the reagent. This makes testing seamless, eliminates manual chemical handling, and reduces the risk of contact or spills. The sealed solvent management system also mitigates excess moisture from getting into the cell
Standby mode keeps the solvent dry between titrations or when the titrator is not in use
Includes a rechargeable, color-indicating, silica gel desiccant. The desiccant changes color to alert users when its absorption capacity is depleted and needs to be recharged or replaced
